It must be inexpensive in the 0w-20 grade, as the Toyota dealer near my parents' house is using it as their bulk 0w-20.

That is very interesting because all the bottled ENEOS oil I've ever seen is imported from Japan.If it is being supplied in bulk would it still be coming from Japan or the Nippon Oil plant in Alabama? Remember, the original Toyota Brand 0W-20 was made and bottled in the Alabama Nippon Oil plant before XOM took over as the supplier.

If Nippon Oil could make bottle their ENEOS and Sustina brands in Alabama that sould drop the price of their product considerably. That's the problem, it's currently over-priced.
